LOCKING-JOINT FOR RAILS.

SPECIFICATION forming part of Letters Patent No. 734,130, dated July 21, 1 903.

Application filed March 4, 1903- To all whont it Huey concern: v

Beitknown that I, PETER F. MCCOOL, a citizen of the United States, residing at Butler,. county of Butler, and State of Pennsylvania, have invented a new and useful-Improvement in Locking-Joints for Rails, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specifica-f tion.

My invention relates to rail-joints.

The objects of the invention are to provide a true lock-joint which will clamp the rails tightly without necessitatingthe use of bolts and also to so construct the jointthat it may be elongated, so as to form a true suspensionjoint that will not only strengthen the joint immediatelyunder the abutting endsofthe rails, but-which will also support the samev from the tieson either side of this point.

In the drawings, Figure 1 is a sectional view of the joint; Fig. 2, a reversed plan view, and

.. Fig. 3 is a sectional view of a modification.

A is the rail. v

B is one part of the joint, and C the other part. The part A extends from the head of the rail downwardly along the web, thenceoutwardly over, around, and under the base,- and terminates at a point immediately belowv the web. At this point the part B is provided with an integral downwardly-extending locking member or key 0, havingtwo lateral extensions c a, forming shoulders o 0 The outer side of each extension is sloped or beveled outwardly and downwardly, "as shown.. The other part D of the jointextends from;

the head of the rail downwardly alongthe Y ing member E forms a keyway for the key 0, and the keyway and key are correspondingly tapered from one end to the other.

The rail-joint is applied to the rail by insorting the smaller end of the key into the Serial No. 146,047. (No model.)

under end of the keyway and driving the part B home. The parts are thus wedged together. The interlocking shoulders and projections of the two locking members cooperate with the ,wedge engagement to securely lock the two parts of the joint together and to securely lock the joint itself to the rails, the beveled :it to be elongated, so as to support the rails.

well'on toward the center or opposite sides of the joint-ties, thus forming a suspensionjoint which prevents the rails from going down under load, or, in other words, rocking while trains are passing over them.

In Fig. 4 I have shown a modification in which the key H of the part Bis provided with but one lateral extension h and shoulder h. In this construction the configuration of the keyway of the locking member K of the part C conforms to that of the key, as in the preferred form, and the key is provided with beveled faces corresponding to the beveled .faces on the extensions c c of the preferred form.

I Havingnow fully described my invention, what I claim, and desire to protect byLetters Patent, is-

1. A two-part joint for rails, one part of which has a locking member .or key extending downwardly and at its lower portion provided with a lateral extension on each side thereof, forming shoulders, and the other 1 2. A two-part joint for rails, one part of.

which has a locking member or key extending downwardly and at its lower portions provided with a lateral extension forming a shoulder, and the other part of which has a complementary locking member extending downwardly, laterally and upwardly and embracing the key and having a projecting part engaging the shoulder thereon, the opposing sides of the two members being tapered in a longitudinal direction, substantially as described.

3. A two-part joint for rails, one part of which has a locking member or key extending downwardly and at its lower portions provided with a lateral extension forming a shoulder, and the other part of which has a complementary locking member extending downwardly, laterally and upwardly and embracing the key and having a projecting part engaging the shoulder thereon, the opposite sides of the two members being tapered in a longitudinal direction, the shoulder and projecting part being each wider at the wider end of the key than at the other end, substantially as described.

4:. A two-part joint for rails, one part of which extends underneath the base of the rail to a point substantially underneath the web and provided at this point with a downwardly-extending locking member or key having a lateral extension forming a shoulder, the outer face of this lateral extension sloping outwardly and downwardly, the other part of the joint extending underneath the base of the rail and havinga complementary locking member extending downwardly, laterally and upwardly and thus embracing the key and also having a projecting part engaging the shoulder formed on the key, the opposing sides of the two locking members being tapered in a longitudinal direction, substantially as described.

5. A two-part joint for rails, one part of which extends underneath the base of the rail to a point substantially underneath the web and provided at this point with a downwardlyextending locking member having a lateral extension on each side forming shoulders, the other part of the joint extending underneath the base of the rail and having a. complementary locking member embracing the key and having also projecting parts, one of which extends between one of said shoulders and the rail-base and the other of which extends between the other shoulder and the firstnamed part of the joint, the opposing sides of the two locking members being tapered in a longitudinal direction, substantially as described.

6. A two-part joint for rails, one part extending on one side of the rail from the head thereof downwardly along the web, thence outwardly along and over the base, thence around and under the base to a point substantially central of the web, said part at this point being provided with a locking member extending downwardly and at its lower portion ,provided with a lateral extension on each side thereof, each of said lateral extensions havingasubstantially horizontal upper surface and a sloping outer surface extending downwardly and outwardly, the other part of the joint extending on the other side of the rail from the head thereof downwardly along the web, thence outwardly along and over the base, thence around and under the base to the lateral terminus of the other part, and being provided at this point with alocking member extending downwardly along one side, laterally under, and upwardly along the other side, of the locking member of the other part, the abutting surface of the looking member of the second-named part conforming in configuration to the locking member of the first-named part so as to continuously embrace the same at every point, substantially as described.

7. A two-part lock-joint for rails, one part extending on one side of the rail from the head thereof downwardly along the web, thence outwardly along and over the base, thence around and under the base to a point substantially central of the web, said part at this point being provided with a locking member extending downwardly and at its lower portion provided with a lateral extension having a substantially horizontal upper surface and a sloping outer surface extending downwardly and outwardly, the other part-f the joint extending on the other side of the rail from the head thereof downwardly along the web, thence outwardly along and over the base, thence around and under the base to the lateral terminus of the other part, and being provided at this point with a locking member extending downwardly along one side, laterally under, and upwardly along the other side, of the locking member of the other part, the abutting surface of the looking member of the second-named part conforming in configuration to the'locking member of the first-named part so as to embrace the same, substantially as described.

8. A two-part joint for rails, one part-extending on one side of the rail from the head thereof downwardly along the web, thence outwardly along and over the base,thence around and under the base to a point substantially central of the web, said part at this point being provided with a locking member extending downwardly and at its lower portion provided with a lateral extension on'each side thereof, each of said lateral extensions having a substantially horizontal upper surface and a sloping outer surface extending downwardly and outwardly, the other part of the joint extending on the other side of the rail from the head thereof downwardly along the web, thence outwardly along and over the base, thence around and under the base to the lateral terminus of the other part and being provided at this point with a locking member embracing the locking member of the other part and conforming in configuration thereto, the opposing lateral faces of the two members being tapered in a longitudinal direction, substantially as described.

9. A two-part look-joint for rails, one part extending on one side of the rail from the head thereof downwardly along the web, thence outwardly along and over the base, thence around and under the base to a point substantially central of the web, said part at this point being provided with a locking memberextending downwardly and at its lower portion provided with a lateral extension having a substantially horizontal upper surface and a sloping outer surface extending down- Wardly and outwardly, the other part of the joint extending on the other side of the rail from the head thereof downwardly along the web, thence outwardly along and over the base, thence around and under the base to the lateral terminus of the other part, and being provided at this point with a locking member, embracing the locking member of the other part and conforming in configuration thereto, the opposing lateral faces of the two members being tapered in a longitudinal direction, substantially as described.

10. A two-part joint for rails, one part of which has a longitudinally-tapered key and the other part of which has a correspondinglytapered keyway, the key having a shoulder and the part forming the keyway having a projection engaging the shoulder, substantially as described.

In testimony of which invention I have hereunto set my hand, at Butler, Pennsylvania, on this 23d day of February, 1903.
